Patent JP-S6298680-A (JP)
Title: Surface light emitting diode
Inventor: HAYASHI JUNJI
IPC: H01L33/14
Filed: 1985-10-24
Abstract: PURPOSE:To increase efficiency to take out light, by concentrating a current in the central part of semiconductor multilayer containing a P-N junction. CONSTITUTION:In a semiconductor layer surround by a groove, a P-N junction 9 is formed which acts as a light-emitting part. The side surface of a P-InP layer 2 in a semiconductor multilayer 12 containing a P-N junction being a current path is eliminated and made hollow, so that the current flowing in the P-N junction 9 is constricted here. Thus the current concentrates in the central part of the P-N junction 9, thereby the current density is made high in the central part of the P-N junction 9, and the light emission intensity increases. Consequently, it is made possible to take out the light with high efficiency, and the light output is extremely increased. Further, the current density in the side surface of the P-N junction 9 is low, so that the nonemitting surface recombination in the side surface of the groove decreases as compared with conventional ones, and the light emission efficiency increases.

Title: Refresh control circuit for memory
Inventor: MURAMATSU GOJI
IPC: G11C11/406
Filed: 1990-09-07
Abstract: PURPOSE:To enable a sufficient refreshing process even in a system whereon a reference clock is not present by periodically generating a refresh demand signal, and allowing one of the signals to output a another one to stand by when an access demand signal and refresh demand signal compete each other. CONSTITUTION:The refresh demand signal is periodically generated by a refresh demand means 101. The normal access demand signal an the refresh demand signal from the refresh demand means 101 are received by a confluence means 102 and one of these demand signals is outputted and another one is made to wait. Further by a control means 104, the normal access or refresh operation is controlled for a memory 105 in response to the output of confluence means 104. Thus, refreshing can be almost periodically performed even if the memory access is irregularly performed.

Filed: 1988-09-26
Abstract: PURPOSE:To reduce weight without increasing size by a method wherein an annular wall is formed on the outer peripheral edge of a plate part, and a cam part provided at its forward edge with a flange and with which a rolling body is connected is formed. CONSTITUTION:A circumferentially extending annular wall 8 is integrally formed on the outer peripheral edge of a plate part 4 through throttle processing, three arcuate parts 8a... and three cam parts 8b are alternately formed at equal intervals on the outer peripheral edge of the plate part.

Abstract: PURPOSE:To enable non-destructive analysis of heat resistant parts or the like, by taking a sample by transferring a precipitate on the surface of material to display the proportion of analyzing points within a desired density range in all analyzing points of a sample in relation to the density. CONSTITUTION:The surface 1 of material is corroded in a corrosion liquid to expose a precipitate 2 and a replica film 3 is applied thereon and dried. Then, the film 3 is peeled off and placed into a vacuum evaporator to form a carbon deposit film 4 on a transfer surface thereof. Thereafter, the film 3 is dissolved to obtain an inspection sample S. An electronic beam 8 is converged from an electron generator 7 to irradiate a sample S. The sample S is moved with a drive controller 9 in directions X and Y and the intensity of characteristic X rays as generated with the irradiation of the beam 8 is detected 11 and stared 12. Then, with an electronic computer 13, the intensity of an X ray signal is converted into element density and analyzing points are classified based on a desired density range and the number of analyzing points within the density range is calculated. Thus, the ratio of the analyzing points involved to all analyzing points is determined as area ratio and outputted and shown on a display device 14 in relation the element density.

Title: Amplitude conversion actuator for ink jet printer head
Inventor: MIYAZAWA HISASHI
IPC: B41J2/045
Filed: 1990-09-10
Abstract: PURPOSE:To make it possible to discharge ink at a low drive voltage by forming a weight part which comes in contact with an oscillation element at the tip of a leaf spring formed in one piece with a base between the oscillation element and a nozzle orifice. CONSTITUTION:If a starting pulse is applied to a piezoelectric amplitude 2, a piezoelectric element 2 becomes stretched sharply and the weight part 1b of an amplitude conversion actuator is pressed by the end surface 2a of the piezoelectric element 2 to come close to a nozzle orifice 3a. If an ending pulse is applied, the piezoelectric element 2 becomes contracted instead of stretched. However, the weight part 1b further approaches the nozzle orifice 3a due to a cycle comprising the relationship between the spring properties of a leaf spring part 1a and the weight of the weight part 1b, as the movement of the weight part 1b in a nozzle orifice direction is not restricted by the piezoelectric element 2. Then the speed is reduced to 0 when the weight part 1b comes in contact with a nozzle plate 3. Next, the weight part 1b shifts to a restoration process due to the spring properties of the leaf spring part 1a and comes in contact with the end surface 2a of the piezoelectric element 2. Thus the device is initialized. A pressure generates due to the oscillation of this movement and ink 4 is discharged from the nozzle orifice 3a in the form of ink droplets.

Abstract: PURPOSE:To minimize the difference in an actual compounding rate after weighing from a specified compounding rate and thereby to improve the compounding precision, by providing a computer with a function of correcting a weighing specifying value on the basis of an actual weighed value. CONSTITUTION:First the name and the weighing value of a mixture to be weighed are inputted from a console 11, and a weighing start instruction is given to a computer 12.

Next, based on these informations, the computer 12 outputs a weighing start signal, as well as a specified weighing value and the tank number, to a weighing control unit 16 through the intermediary of a process input/output unit 15, for each one material. Then, according to the instruction of the weighing control unit 16, a weigher 17 starts weighing the material, while monitoring an actual weighed value simultaneously. When the actual weighed value gets in a range of the specified weighing value + or -(a), the unit 16 gives the weigher 17 an instruction on the completion of weighing, outputting a weighing completion signal and the actual weighed value to the computer 12 through the input unit 15. Receiving the actual weighed value, the computer 12 calculates a specified weighing value for a subsequent material for which the error thereof from the specified weighing value is corrected.

Abstract: PURPOSE:To extrude a resin into a mold under a uniform state, and to obtain uniform products by forming a path between a resin charge port and the mold to a zigzag manner, reducing the impact of the resin injected into the mold and equalizing the temperature of the injected resin. CONSTITUTION:A resin charged from a pot section 1 is constricted by the constriction section 5 of a projection section 2a in a path 2 and a gate 3, and injected into a cavity 4 in a mold. Accordingly, since the path 2 is formed to a zigzag manner, the pressure of the resin injected into the cavity 4 is weakened, and a part such as a semiconductor inserted into the cavity 4 is not damaged and is coated with the resin. Since the resin is also kneaded sufficiently, the resin is heated uniformly, and products having uniform quality are obtained.

Title: Film inspecting device
Inventor: KIMURA HIROAKI
IPC: G01N21/89
Filed: 1988-09-27
Abstract: PURPOSE:To accurately detect a fish eye included in a film by performing image pickup with a one-dimensional CCD in a range obtained by being moved in parallel from an illuminating position to the film by a line-shaped transmitting illumination. CONSTITUTION:The film 3 is illuminated with the transmitted light from a line-shaped light source 5, which is near the collimated beam of light, and the one-dimensional CCD 1 is set to perform image pickup in the range 4 obtained by being moved in parallel from the illuminating position to the film 3 so that the transmitted light can not be received. Therefore, the output from the CCD 1 in the normal part of the film 3 and the part where dust exists thereof becomes low and the output from the CCD 1 in the part where the fish eye 6 exists becomes high because the light is scattered. Thus, the dust stuck to the film 3 is not detected but only optical distortion where gel, etc., is taken as a core can be detected with a simple constitution.
